FIELD OF THE INVENTION

The present invention relates to a multi piece modular frame for use inan active grille shutter system for a vehicle.

BACKGROUND OF THE INVENTION

Various attempts have been made to optimize the cooling of variousautomobile parts. Some of the various devices developed have beendesigned to control the air flow throughout the engine compartment ofthe automobile such that the desired amount of heat is transferred awayfrom the engine, transmission, and other components which generate heat,in order to maintain an optimal operating temperature.

However, it is also desirable to bring the engine up to the normaloperating temperature as soon as possible after engine start-up. Whenthe engine is substantially the same temperature as the surroundingenvironment and is turned on, the engine is the least fuel efficient(especially during start-up and the temperature of the surroundingenvironment is cold). The reduced fuel efficiency is why it isconsidered desirable to bring the engine up to the optimal operatingtemperature very quickly. Under these conditions, it is not desirable toremove heat away from the engine and the various components surroundingthe engine, and therefore devices designed to control air flow aroundthe engine are more beneficially used if they do not remove heat awayfrom the engine at start-up.

Active grille systems that have been developed implement a frame istypically molded as a complete part. During assembly, the frame and/orthe vanes have to be distorted in order to assemble the complete systemonto the one piece frame. Additionally, the one piece frame has a lowshipping density as it is mostly empty space. Furthermore, if an activegrille system has two variants with either additional vanes or a baseair flow, a complete new frame must be molded and shipped. It istherefore desirable to provide a frame that is multiple separate moldedparts instead of one complete molding. This will aid in the assembly ofthe active grille shutter system without having to distort the frames orthe vanes. Additionally, having multiple components accommodates thevarious variants that can be needed depending on the particularapplication. Lastly, having a multi-piece frame increases the shippingdensity since the various components can be stacked more closelytogether.

SUMMARY OF THE INVENTION

The present invention is directed to an active grille shutterarrangement having a modular frame. The active grille shutterarrangement includes a primary frame piece defining a width and heightof an aperture of the modular frame, wherein in the primary frame piecehas a motor housing, and upper frame portion having a first end and asecond end, a lower frame portion having a first end and a second endand the motor housing extends between the upper frame portion and thelower frame portion. There is a plurality of secondary frame piecesincluding a first end cap, connectable to the first respective end ofthe upper frame portion and the first end of the lower frame portion byan upper bar and joint formed on the first end of the upper frameportion and a lower bar and joint formed on the first end of the lowerframe portion. A second end of the plurality of secondary frame piecesis connectable to both the second end of the upper frame portion and thesecond end of the lower frame portion by an upper bar and joint formedon the second end of the upper frame portion and a lower bar and jointformed on the second end of the lower frame portion. The modular frameof the active grille shutter arrangement is formed by the connection ofthe primary frame piece in the secondary frame piece, where in themodular frame defines the aperture. The active grille shutterarrangement further includes a plurality of vanes rotatably positionedbetween the first end cap and the second end cap for controlling theamount of air flowing through the one or more apertures of the modularframe.

Referring to FIGS. 2A, 2B, 2C and 4, another aspect of the invention isshown that includes a modular frame kit 13 (shown in FIG. 4), includingparts of varying sizes used to create different modular frames. Themodular frame 12 is a first modular frame having a different height andwidth from a second modular frame 12′ or third modular frame 12″. Thefirst modular frame 12, second modular frame 12′ and third modular frame12″ are created by using the different alternate parts shown in FIGS.2A, 2B, 2C and 4, which include the upper frame portion 14, that is afirst upper frame portion, a second upper frame portion 14′, third upperframe portion 14″, the second lower frame portion 20 that is a firstlower frame portion, a second lower frame portion 20′, third lower frameportion 20″, vanes 34, that are a first vanes, second vanes 34′ andthird vanes 34″ (shown in FIGS. 2A, 2B and 2C) all of which havingdifferent widths. The modular frame kit 13 further includes end caps 26,28 that are a first set of end caps, a second set of end caps 26′, 28′and a third set of end caps 26″, 28″ each having different heights. Alsothe modular frame kit 13 includes the motor housing 36, which is a firstmotor housing, second motor housing 36′ and third motor housing 36″ eachhaving a different height and can be interchanged with the other partsof the modular frame kit to form the first modular frame 12, secondmodular frame 12′, third modular frame 12″ as shown in FIGS. 2A-2C.During assembly one upper frame portion, one lower frame portion, onemotor housing and one set of end caps is selected to create a desiredmodular frame construction. The selected one of the set of end caps isconnected to respective opposing ends of the one selected upper frameportion and one selected lower frame portion forming a generallyrectangular or square frame. The one selected motor housing is connectedbetween the one selected upper frame portion and the one selected lowerframe portion.

It is also within the scope of this invention for the parts of themodular frame kit 13 to be used in other combinations to create othermodular frame constructions having a height, width and shape that willvary depending on the different components used. It is further withinthe scope of this invention for the modular frame kit to have a greateror lesser number of alternate components having different dimensions andis not limited to just three alternative parts.

The modular frame kit 13 provides a great deal of versatility for thevarious components since the modular frames 12, 12′, 12″ can have adifferent size assembled from parts having different lengths. Thisallows the modular frame 12, 12′, 12″ to be used with various variantsencountered in and incorporating active grille shutter arrangements onvehicles. This also increases the shipping density of the components ofthe modular frame 12, 12′, 12″ by allowing similar parts to be packagedtogether more tightly than would be possible with a modular frame thatis one piece.
